Specification of Letters Patent.

Application filed June 5, 1911.

Serial No. 631,251.

To all whom it may concern Be it known that I, THOMAS P. CALLIGOTT, acitizen of the United States, residing at Prescott, in the county ofNevada and State of Arkansas, have invented certain new and usefulImprovements in Churns, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to improvements in churns of that type employinga vertical reciprocating dasher and has for its primary object theprovision of simple and efficient means whereby the dasher may be easilyand quickly connected or disconnected to and from the reciprocatingpitman.

A further object of the invention is to provide a vertical frame havinga crank shaft mounted therein, a pitman connected to the crank shaft, asectional block connected to.

said pitman, and a novel guide-way for said block whereby the sectionsmay be separated to remove the shank of the dasher whereby the same isdisconnected from the pitman.

Another object of the invention is to provide a very simple and durable'construction of the above character, such construction enabling thedasher -to be removed and cleaned whereby the churn is maintained in asanitary condition.

With the above and other objects in i iew,

the invention consists of the novel. features of construction,combination and arrangement of parts hereinafter fully described andclaimed, and illustrated in the acconrpanying drawings, in which Figure1 is a front elevation of a churn embodying my improvements; Fig. 2 is asection taken on the line 2-2 of Fig. 1; Fig. 3 is a section taken onthe line 33 of Fig. 2; and Fig. 4c is a detail perspective view of oneof the sliding block sect-ions and a fragment of the dasher shank.

Referring in detail to the drawing 5 designates a vertical frame whichconsists of the lower spaced uprights or legs 6 and the body 7. Thisbody is provided with a lon-- gitudinal slot 8. Upon the upper end ofthe frame a crank shaft 9 is mounted in suitable bearings 10, the crank9 of the shaft being disposed in the slot 8 of the frame. To the crank 9one end of a pitman 11 is connected, said pitman being adapted to workin the slot 8. One end of the crank 9 is provided with a handle 12 andto the other end thereof a belt wheel 13 is secured. This wheel istraversed by the driving belt 14 which passes around a belt wheel 15mounted in a suitable bearing 16 secured to one of the spaced legs 6 ofthe frame. The shaft 17 of this lower belt wheel also has a hand crankformed on each of its ends whereby said belt may be moved to rotate theupper crank shaft 9 and impart reciprocatory movementto the pitman 11.

The body 7 of the frame structure below the slot 8 is provided with avertical groove or channel 18 in line with said slot and in this groovethe sliding block sections 19 and 19 are arranged. These block sectionsat one of their ends are bifurcated as indicated at 20 and they are eachprovided with the bearing recesses 21 to receive the ends of a wrist pin22 which is fixed in the lower end of the pitman 11. The block section19 is rabbeted at its opposite longitudinal edges as indicated at 23 toreceive the opposed edges of the movable retaining bar sections 25 whichare hingedly connected tothe stationary sections 24 by means ofsuitablehinges 26. The'lower ends of the movable sections 25 are provided withsuitable thumb screws 27 which are adapted to be threaded into the frame5' to rigidly secure said movable sections upon the frame. When sodisposed it s will be obvious that all tendency of the block sections 19and 19 to move out of the channel or groove 18 in the frame is overcome.

The lower ends of the sliding block sections 19 and 19' are alsoprovided with the substantially triangular-shaped recesses 28 whichreceive the flared rectangular end 30 of the dasher shank 29. By thusconnecting the dasher to the sliding blocks, it will be seen that in theoperation of the device, a reciprocatory movement will be imparted tothe dasher, and all liability of its disconnection from the slidingblock sections is obviated while at the same time, when the churningoperation is completed the dasher may be readily removed.

In the practical use of my invention, the churn vat or tub is arrangedbetween the ends of the uprights or legs '6 of the frame which arepreferably secured upon a suitable base, and the movable retaining barsections 25 are raised. The outermost block section 19 is then liftedfrom the face of the other block section 19 and the flared end 30 of thedasher shank is seated in the recess 28 of the last named block section.The outer section 19 is then disposed upon the same, the bearingrecesses 21 receiving the rights 6;

wrist pin 22 of the pitman. The lower movable bar sections 25 are thenreturned to I their normal positions and rigidly fastened upon the framebody by means of the screws 27. The device is now in condition to beoperated by simply turning either of the cranks 9 or 17. When thechurning operation has been completed, the dasher is removed in asimilar manner, so that it may be readily cleaned and the churn vatremoved from'its position between the up- T the various parts, it willbe understood that the device is susceptible of considerable Imodification without'departing from the essential feature or sacrificingany of the adl vantages thereof.

Having thus described the is claimed is,:

l. The combination with a frame having a vertical guide-way, of areciprocating piston and operating means therefor mounted in the frame,block sections arranged upon invention what each other and movable insaid guide-Way, said pitman being pivotally connected at one end to saidblock sections, retaining bars be rigidly secured to the frame.

2. The combination with a frame, of a reciprocatory pitman and operating-means therefor, said frame having a guide-way, block sections slidablein said guide-way and pivotally connected to said pitman, one of saidblock sections having its opposite longitudinal edges rabbeted, saidsections being arranged upon each other and provided in their opposedfaces with recesses to receive the end of a dasher shank, retaining barssecured upon the frame and extending upon the rabbeted edges of saidblock sections, said bars each including a stationary section and amovable section hinged to the stationary section, and means for rigidlysecuring the movable retaining bar sections to the frame.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
